Answer»

An inorganic compound (A) shows the following reactions

i) It is white solid exists as dimmer and gives fumes of (B) with wet air

ii) It sublimes in $180^{\circ} C$ and form monomer If heated to $400^{\circ} C$

iii) Its aq solution turns blue litmus to red.

iv) Addition of $N H_{4} O H$ and NaOH separately to a solution of (A) gives white ppt

which is however soluble in excess of NaOH. What is 'A'
